Start with recurrence
A one-off oversight may be noise. Repeated trouble in similar phases or situations deserves your attention first.
Recurring mistake review
A Chess Blunder Checker for Patterns That Keep Coming Back
A red question mark can tell you a move was costly. It cannot tell you why the same kind of decision keeps appearing. Chessigma looks for repeatable leaks in your playing history so your review ends with a useful habit to change.
A repeatable process
Check the habit behind the mistake
Name the decision pattern
Turn a vague “I blunder too much” into a specific observation about your openings, pace, or recurring game outcomes.
Create a small constraint
Use one review question or practice rule in your next session, rather than trying to eliminate every error at once.
Know the boundary
Not a Stockfish blunder detector
Chessigma does not assign engine evaluations, centipawn loss, or tactical accuracy labels. “Blunder checker” here means checking your history for repeated behavioral patterns that may be leaking results.
What you leave with
- ◆Separate one-off errors from recurring leaks
- ◆Focus practice on patterns you control
- ◆Review mistakes without fake engine precision
Questions, answered plainly
Will Chessigma label moves as blunders?
No. It identifies history-level patterns rather than engine-defined move classifications.
Is this useful alongside an engine?
Yes. An engine can examine a position; Chessigma adds the longer view of what repeats across your games.
